ppmmix - blend together two portable pixmaps
ppmmix fadefactor
ppmfile1 ppmfile2
Reads two portable pixmaps as input. Mixes
them together using the specified fade factor. The fade factor may be in
the range from 0.0 (only ppmfile1's image data) to 1.0 (only ppmfile2's image
data). Anything in between gains a smooth blend between the two images.
The
two pixmaps must have the same size.
pnmcomp is a more general alternative.
It allows you to mix images of different size and to have the fade factor
vary throughout the image (through the use of an alpha mask).
